{"product_id":"brightwell-aquatics-phosphat-e-500-ml","title":"Brightwell Aquatics Phosphāt-E Liquid Phosphate Remover, 500 ml, for marine fish and reef aquariums","description":"\u003cp\u003eDose this liquid phosphate remover into marine fish and reef aquariums, pouring the measured amount where a mechanical filter or protein skimmer draws water in. A 500 ml bottle reaches up to 8,000 US gallons, and the daily maximum is 2.5 ml per 20 gallons, a dose that removes 0.5 ppm of phosphate.\u003c\/p\u003e\u003ch2\u003eChecks before the first dose\u003c\/h2\u003e\u003cp\u003ePhosphāt-E suits marine fish tanks, reef tanks and freshwater aquariums. A phosphate test result is the starting point: measure the tank's concentration with an accurate kit before the first use, because the numbers in the dose table are built around that reading. Each 250 ml of product covers 1,000 gallons, so a 500 ml bottle handles twice that volume; the initial application eliminates 1 ppm of reactive phosphate in 4 gallons.\u003c\/p\u003e\u003cp\u003eTwo things happen after dosing. The tank may turn slightly cloudy right after the product goes in, which the brand describes as normal and temporary. Phosphate kits can also return a false positive after treatment, because of how the test chemistry reacts with the product.\u003c\/p\u003e\u003ch2\u003eAdding Phosphāt-E to the system\u003c\/h2\u003e\u003cp\u003eDose no more than 2.5 ml per 20 gallons in a single day, which reduces phosphate by 0.5 ppm. Pour the measured amount beside the mechanical filter or at the skimmer's water intake, as the directions state. The process can be repeated on a continuing basis for phosphate reduction.\u003c\/p\u003e\u003ch2\u003eWhat the bottle holds and covers\u003c\/h2\u003e\u003cp\u003eThe product leaves 1 ppm of reactive phosphate out of 4 gallons of water each time it is applied, and the daily 2.5 ml per 20 gallon dose brings phosphate down by 0.5 ppm.\u003c\/p\u003e\u003cp\u003eFreshwater tanks are included alongside reef and marine fish systems, so the same bottle serves more than one type of aquarium. The model number is POE500, and the included component is the Phosphāt-E bottle itself.\u003c\/p\u003e\u003ch2\u003eQuestions about dosing and use\u003c\/h2\u003e\u003ch3\u003eHow far does one bottle go?\u003c\/h3\u003e\u003cp\u003eUp to 8,000 US gallons, based on 250 ml per 1,000 gallons. That is twice the 4,000 US gallons a 250 ml bottle handles.\u003c\/p\u003e\u003ch3\u003eWhat is the largest daily dose?\u003c\/h3\u003e\u003cp\u003eThe maximum is 2.5 ml per 20 gallons of tank water per day. At that rate, phosphate falls by 0.5 ppm.\u003c\/p\u003e\u003ch3\u003eWhere in the aquarium should I add the product?\u003c\/h3\u003e\u003cp\u003eBeside a mechanical filter or at a protein skimmer's water intake, so the dose stays close to the filtration equipment.\u003c\/p\u003e\u003ch3\u003eDoes it work in a freshwater tank?\u003c\/h3\u003e\u003cp\u003eYes, it is safe for freshwater aquariums as well as reef and marine fish environments. The same dosing and application directions apply.\u003c\/p\u003e\u003ch3\u003eWhy does my phosphate test show a reading after treatment?\u003c\/h3\u003e\u003cp\u003ePhosphate test kits may give false positive results after dosing, because of the chemical mechanism the kits use. The cloudiness some tanks show right after application is normal and temporary.\u003c\/p\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eModel\u003c\/th\u003e\n\u003ctd\u003ePOE500\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eItem form\u003c\/th\u003e\n\u003ctd\u003eLiquid\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eTarget audience\u003c\/th\u003e\n\u003ctd\u003ealgae-eaters\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSize\u003c\/th\u003e\n\u003ctd\u003e0.5 l\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eItem dimensions (L x W x H)\u003c\/th\u003e\n\u003ctd\u003e2.5 x 2.5 x 2.5 cm (1 x 1 x 1 in)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eItem weight\u003c\/th\u003e\n\u003ctd\u003e454 g (1 lb)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eIncluded components\u003c\/th\u003e\n\u003ctd\u003ePhosphat-E\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSpecific uses\u003c\/th\u003e\n\u003ctd\u003efish\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e","brand":"Brightwell Aquatics","offers":[{"title":"Default Title","offer_id":44474378092607,"sku":null,"price":84.64,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0678\/2409\/1199\/files\/brightwell-aquatics-aquarium-water-treatment-500ml-4.jpg?v=1794653855","url":"https:\/\/dogjointly.com\/products\/brightwell-aquatics-phosphat-e-500-ml","provider":"DogJointly","version":"1.0","type":"link"}
